I would like to start a new thread regarding issues with the phone's touchscreen since the original thread here was marked as solved in March 2016, but the promised update doesn't exist or doesn't seem to resolve the issue.
I have a black Z5 Compact since November 2015. For some months now my touchscreen has been acting weird. After some minutes of usage the lower half of the screen is partially overreacting - meaning repetitve and/or displaced input - and partially not reacting at all. The issue appears to be triggered faster when the phone is being charged (also when using the original charger and cable), and considering the higher temperature of the phone during this time, the problem could be connected to overheating. In any case, the problem can be solved temporary by switching the screen off and on. However, since it can happen every few minutes, this is not a permanent solution. I tried several of the suggested fixes, namely removing the additional case, switching to safe mode, removing the sd card and even repairing and updating the phone using PC Companion (including losing lots of data). The last one apparently even increased the frequency of the problem.
I'm disappointed by Sony and right now I'm not thinking of buying another phone of the company since these problems emerged already when the phone was introduced and the promised solution was apparently removed in a later update. But I'm also not willing to give up an otherwise really good phone that's just 2 years old and I hope that Sony will remember how to treat their customers especially if they want to keep them.
